The Cartwheel Galaxy shows a ring that is the result of a collision between a small and a large galaxy.
车轮星系呈现出一个由大小两个星系碰撞而形成的光环。

After collision, the energy condenses to create new particles that can be measured and tracked inside the complex particle detectors around the accelerator ring.
对撞之后，这些能量会生成一些新的粒子，它们可以在围绕着加速环的复杂粒子探测器里被测量并跟踪。

The collision between the two parent galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring.
